BGA125N6Ultra Low Current Low Noise Ampli f ier for L2/L5 GNSS Appl icat ions

Features

• Operation frequencies: 1164 to 1300 MHz• Ultra low current consumption: 1.3 mA• Wide supply voltage range: 1.1 V to 3.3 V• High insertion power gain: 20.0 dB• Low noise figure: 0.80 dB• 2 kV HBM ESD protection (inluding AI pin)• Ultra small and RoHS/WEEE compliant package 0.7 x 1.1mm2

Potential Application

The BGA125N6 is designed to enhance GNSS signal sensitivity for band L2/L5 especially in wearables and mobilecellular IoT applications. With the very good performance it ensures high system sensitivity. The ultra low powerconsumption of 1.5mWpreserves valuable battery power, ideal for small battery poweredGNSSdevices. Thewidesupply voltage range from 1.1 V to 3.3 V ensure flexible design and high compatibility. Besides GPS L2 and L5, theGNSS LNA also covers Galileo E5a, E5b, E6, Glonass G3, G2, Beidou B3, B2 and IRNSS/NAVIC bands.

Product Validation

Qualified for industrial applications according to the relevant tests of JEDEC47/20/22.
